[ruby/prism] Fix a diagnostic incompatibility
This PR fixes a diagnostic incompatibility when using no anonymous keyword rest parameter:
```ruby
foo(**)
```
Note, although the actual update applies only to the `foo(**)` case, for reference,
`foo(*)` and `foo(&) are also mentioned below.
## Ruby (Expected)
```console
$ ruby -cve 'foo(*)'
ruby 3.3.0 (2023-12-25 revision https://github.com/ruby/prism/commit/5124f9ac75) [x86_64-darwin22]
-e:1: no anonymous rest parameter
-e: compile error (SyntaxError)
$ ruby -cve 'foo(**)'

```
## Prism (Actual)
Before:
```console
$ bundle exec ruby -Ilib -rprism -wve 'p Prism.parse("foo(*)").errors'
